You can change the programming of your key fobs at home, however you must be aware of the correct procedure. To get the best results, you must have the following items:
Keys
The majority of modern vehicles require a transponder keys to operate. This provides security and protection against theft. The keys have to be programmed to your specific vehicle and its systems by a licensed dealer or locksmith. They are expensive to replace if lost, so you should have spares in your car. You can also find replacement keys fobs at various online stores and in a variety of brick-and-mortar automotive shops. How can you ensure that the key you purchased is authentic? Do you know if the unit has been programmed to work with a different vehicle or if it could be programmed differently?
To program a new car key, you must first verify that your car is running. Insert the key you want to program into the ignition, but don't turn it. You will only have just a few seconds before the car's system resets the commands and then exits programming mode. It is important that you be quick and don't delay between each step. Stop the engine to prevent this. You can check the car's system by turning the key to the "on" position and then back to the "off" position. The door locks should cycle and you will hear a chime signalling that the process has been successful.
Certain newer vehicles utilize rolling key technology to prevent thieves from using stolen keys to start the vehicle. This feature is still vulnerable to a method known as a replay attack, which allows thieves to record the signal from the key fob on the vehicle and then replicate it to unlock the car. To stop this, manufacturers have added the security feature known as the CAN bus protocols to prevent hackers from gaining access to the vehicle.
Certain manufacturers have a unique encryption on their keys, which cannot be decoded by an ordinary program. It is best to only attempt this method if your previous experience is in electronic devices. Consult your car's manual or look up the website of the manufacturer to find out how to program it. The steps to follow will differ depending on the type of vehicle.
Transponder chips
Car keys with transponder chips require a special reprogramming to function. Any hardware store can make you an entirely new car key, but the real challenge is in integrating it with your car. The key has to be programmed to match the exact identification code on your car, or else it won't start.
Transponder chips are a common feature of modern cars and are designed to prevent car theft. The chip is a microcircuit which transmits a radio frequency signal when the key is placed in the ignition. The car then detects the signal and begins the engine if it matches the original signal that was programmed into the vehicle. The car also shuts down if a frequency is invalid. This makes it harder for thieves who aren't experienced to wire a vehicle hot and then start it.
A circuit board equipped with an induction coil that connects the chip to the key. When the key is inserted into the ignition it creates an electric field around the transponder. This creates a signal that gets amplified by the coil which then transmits it to key's identification number. The key's identification number is sent back to the car and the engine is started if the identification number matches.
There are a variety of ways to program a transponder, but all of them require the use of a specific tool. You can buy these tools online or from most automotive locksmiths. They are not cheap, but they are essential for programming the chip in your vehicle.
You can also use an reprogrammable key that was previously programmed for a different vehicle. In this scenario, make sure the key hasn't been damaged or the transponder isn't altered in any way. The chip can be read using a scanner, or a computer equipped with a USB connector.
Reprogramming the transponder is a straightforward procedure, but requires special software. It also requires a scanner tool. It's best to ask an auto locksmith for help in case you're not an expert. Avoid buying used keys as they may already be programmed, and they won't work with your car.
EZ Installer
In the past, car owners who wanted to replace their key fob were forced to visit an agent to have it electronically paired with the vehicle. This is because modern keys have to be "paired" to the vehicle of the owner in order to work, which required the use of expensive and complicated equipment that only dealers had access to. The EZ Installer from Car Keys Express solves this problem for locksmiths and retailers by making it easier for pairing modern keys with vehicles.
The Easy Installer, a straightforward "plug-and-play" OBD device, pairs new keys with vehicles without the use of complex equipment or tokens for programming. It works by connecting directly to the vehicle's standard OBD port, and then using a mobile app to provide simple-to-follow instructions. The EZ Installer works with all newer models that have proximity keys or push button start. To determine if it'll work for a particular vehicle, look up the compatibility guide on the Tom's website.
If the device is unable to program the remote or key purchased from Tom's into a compatible vehicle, a full refund is provided.
Contrary to conventional programming equipment which costs retailers and key professionals tens of thousands of dollars in "token" fees per key, the EZ Installer Pro does not charge these costs. It can be used for as long as a key professional or retailer needs. The EZ Installer eliminates the need for expensive monthly service contracts and software updates. This lets retailers save money while providing their customers the same top quality service as OEM equipment. It also offers a top warranty that covers hardware and software for the remainder of your life.
